One of the early concerns about the PSP was that it would end up being a dumping ground for barely tweaked ports of existing PS2 games. Although Tony Hawks Underground 2: Remix is little different from the console originals, its a game that benefits greatly from going portable.The original games freedom of choice -- go anywhere and do anything -- works particularly well when youre gaming on the move, allowing you to dip in for a quick mess around, while the story mode and more complex challenges can be tackled when youve got more time to play.Although most of the game is the same as before, there are four tricky new levels to explore. Indeed, "tricky" could be used to describe a lot of Tony Hawk Underground: without the use of the PS2's twin analogue sticks, the game's control system can be awkward. Although a brand new game in the franchise, specifically made for the PSP, wouldve been ideal this is still a superior slice of gaming the likes of which has never been seen on a portable before. -- Harrison Dent
